A movie so horny it could only be made under the production code. From an interview with director Joseph H. Lewis:
"I told John 'your cock's never been so hard,' and I told Peggy 'You're a female dog in heat, and you want him. But don't let him have it in a hurry. Keep him waiting.' That's exactly how I talked to them and I turned them loose. I didn't have to give them more directions."
